With the rise of renewable energy, there has been increasing demand for gas turbines that can start rapidly and follow the fluctuating load as peak power sources. As a solution to meet the demand, Mitsubishi Power, Ltd. (Mitsubishi Power) offers sets of 300 MW class gas turbine power generation equipment. In some cases, the generator used for the equipment may be desired to be an air-cooled generator that is easy to operate and maintain and we have been developing a 350 MVA class air-cooled generator. This time, we have confirmed that all the performances of the developed generator satisfy the standards by conducting actual equipment verification. This generator has achieved a capacity increase of about 1.5 times that of Mitsubishi Power's conventional air-cooled generators.
